Embodiment 1

[0089] Specifically, the positioning structure 70 includes a positioning portion 71 for directly or indirectly positioning the position of the magnetic steel 20 .

[0090] The positioning structure 70 includes a positioning portion 71 , and using the positioning portion 71 to locate the positions of the plurality of magnets 20 is beneficial to improving the positioning speed of the positions of the magnets 20 , thereby improving the magnetization efficiency. Wherein, the number of positioning parts 71 can be equal to or not equal to the number of magnets 20, and can be used to directly locate the position of magnets 20, and can also be used to indirectly locate the position of magnets 20 . For example: some positioning parts 71 directly correspond to the center position of the magnet 20 and are used to directly locate the position of the magnet 20 , and some positioning parts 71 are located on both sides of the magnet 20 and are used to indirectly locate the position of the ma...

Embodiment 2

[0099] The difference from Embodiment 1 is that the number of positioning parts 71 is equal to the number of magnets 20 , and multiple positioning parts 71 cooperate to indirectly locate the positions of multiple magnets 20 .

[0100] Furthermore, a plurality of magnetic steels 20 are evenly distributed along the circumferential direction of the rotating shaft, and the positioning part 71 is located at the center between two adjacent strip structures, as Figure 6 shown.

[0101] The positioning part 71 is located in the center between two adjacent strip structures, and the middle position of the two positioning parts 71 is a magnetic steel 20, such as Figure 6 shown.

Embodiment 3

[0103] The difference from Embodiment 1 is that the line connecting the center of the strip structure and the center of the end face of the rotor passes through the positioning part 71, such as Figure 7 shown.

[0104] The connecting line between the center of the strip structure and the center of the end face of the rotor passes through the positioning part 71, then the connecting line between the center of the positioning part 71 and the center of the end face of the rotor must pass through the center position of the magnetic steel 20, and the magnetizing head faces the positioning part 71, and it is also exactly The center position of the magnet steel 20 can be accurately magnetized to the magnet steel 20 .

Abstract

The invention provides a rotor, a motor, a water pump and a vehicle. The rotor comprises a rotating shaft, a rotor core and a plastic-coated bod, wherein the rotor iron core is sleeved on the rotatingshaft and synchronously rotates with the rotating shaft, and magnetic steel is arranged in the rotor core; and the plastic-coated body completely wraps the part of the rotor core exposed out of the rotating shaft, forms an integrated structure together with the rotor core and the rotating shaft, and is provided with a positioning structure for positioning the position of the magnetic steel. According to the rotor provided by the invention, the plastic-coated body completely wraps the part of the rotor core exposed out of the rotating shaft, so that the rotor core can be stably and firmly sealed in the plastic-coated body, the situation of displacement, even separation and the like cannot occur, the use reliability of the motor is improved, and in the meantime, complicated processes such as the fixing of fasteners are omitted, which simplifies the production process and improves the preparation efficiency; and the positioning structure on the plastic-coated body can accurately positionthe magnetic steel, so that the magnetizing position of the magnetic steel is accurately positioned, and the magnetizing accuracy is improved.
